Archival Grade Gold DVD-R
Show Products
Manufactured using proprietary, unique dual reflective layers, these discs maximize both compatibility and longevity. To further extend media life, UltraLife™ Gold Archival Grade DVD-R’s contain a hard coating on the recording side to protect surface from scratches. In proper environmental conditions, these discs are designed to last as long as 100 years.
The specifications refer to “dual reflective layer technology” – is this a Dual Layer DVD (DVD-R DL)?
No. In terms of storage capacity, the UltraLife™ Gold Archival Grade DVD-R discs are single layer discs with a 4.7GB storage capacity.
Why 2 layers? What purpose does each layer serve?
The highly reflective silver layer allows the Ultra-Life DVD-R to look like a standard silver disc to DVD drives and burners, providing a low initial error rate and the same drive read/write compatibility as standard silver-only discs. The gold reflective layer, naturally resistant to corrosion, prevents oxygen from corroding the silver reflective layer, a common factor in limiting the life of DVD media.
What is AZO™ Technology?
AZO™ recording dye is a patented technology, which provides the highest level of read/write performance, reliability and archival life for your DVD Recordable media.
Can I record over data on an UltraLife™ Gold DVD-R?
No. Like other DVD Recordable media, UltaLife™ Gold DVD-R’s are single layer DVD discs designed for one-time recording.
